He wants a second chance...she's afraid to risk it. When faced with a choice between two strong-willed men, Sara chooses neither and embarks upon her life as a single mom. When a work crisis forces her to call on the last person she wants to ask for help with a child-care snafu, Jack saves the day-and cements his resolve to get Sara and their daughter back in his life. But Sara's doubts linger, even as they ease their way into co-parenting Katie. Jack turns the full force of his energy on convincing her they should be a family, rejecting her suggestion that they return to their sex-only arrangement even as she rejects his repeated marriage proposals. They have too much history to keep it casual, but as their shared friendships, family, and work keep forcing them together, Sara must choose: the independence she fought so hard for, or a bigger, riskier, love that could last a lifetime. What starts as a forbidden, age-gap rivals-to-lovers runs the gamut of heat and emotion all the way through proposals, cohabitation, break ups, love triangles, and second chances. Don't miss this compelling, realistic, humorous, and happily ever after trilogy.
